China's Artificial Sun Just Broke a Record

In a new world record, China's "artificial sun" project has sustained a nuclear fusion reaction for more than 17 min. Superheated plasma reached almost 70 million degrees C— that's roughly five times hotter than the sun.

Chinese Fusion Experiment Reaches 100 Million Degrees

The Chinese EAST reactor team was able to integrate four types of heating power in order to reach a new temperature record - a cloud of charged particles that contained electrons heated to more than 100 million °C.
